Charge your phone and generate some light with this new add-on kit for your bike.
The EcoXPower kit by EcoXGear uses pedal power to charge your smartphone and an LED lighting system for your bike, keeping you road safe at all hours. Kits for charging your cell phone while riding your bike are not new, but this is the first we know of that also lets you power ultra-bright LED lights too. You may never have to worry about replacing your headlamp again.
